What is a proper alternative for pluck(col_name)

This is a pretty common operation in my toolbox. I want a pure tidyverse solution without using a character.

suppressWarnings(library(tidyverse))
tibble(a=1) %>% pluck('a')
#> [1] 1
tibble(a=1) %>% pluck(a)
#> Error in list2(...): object 'a' not found

Solution

  • We may use pull

    tibble(a =1) %>%
   pull(a)
[1] 1

    Or if we want to use pluck

    tibble(a=1) %>% 
 pluck(deparse(substitute(a)))
[1] 1
